PLOW.

Specification of Letters Patent.

Patented Oct. 25, 1910.

To all whom it may concern:

Be it known that I, WILLIAM A. BLIZ- ZARD, a citizen of the UnitedStates, and resident of Dillon, county of Marion, State of SouthCarolina, haVe invented certain new and useful Improvements in Plows, ofwhich the following is a specification.

This invention relates to plows, and more particularly to plows whichare used for cultivating purposes.

The object of this invention is to construct a plow which willefliciently cultivate and break up the ground.

The invention will be described in connection with the accompanyingdrawings, in which- Figure 1 is a side view of the plow sweep attachedto the stock; Fig. 2 is a front view of the sweep; Fig. 3 is asection onthe line 3-3 Fig. 2; and Fig. 4 is a section on the line 4-4 Fig.- 2.

Referring to the drawings, 10 designates a plow stock, which may be anupright stock of well known construction provided with the usual footpiece 11, which forms the bearing on which the plow runs. A plow sweep12 is provided with a shank 13, which has formed therein an elongatedslot 14 arranged to receive a bolt 15, by means of which the sweep canbe adjustably secured to the stock.

The sweep has formed thereon a pair of outwardly and rearwardlyextending wings 16, the lower edges 17 forming a forwardly projectingpoint 18. The wings terminate rearwardly in substantially verticallyarranged edges 19 which flare outwardly and terminate in sharp corners20. The lower edges 17 are sharpened from the point 18 to the edges 19,as shown in the figures. The wings also terminate rearwardly insubstantially horizontally arranged edges 21, and the rear portions ofthe wings are concave and slightly turned over at 22, as shown in Fig.4. The point 18 is arranged so as to project downwardly slightly, asshown at 23 in Figs. 1 and 2, and the sweep rearwardly of the point isconcave, as shown at 24.

By means of the slotted connection of the sweep to the stock the depthof the cut may be readily adjusted. The construction of the point andthe concave construction in the center at 24 allows the sweep to startinto-the ground easily. The sharp corners 20 and parts of the edges 19run under the ground next to the growingstuif and these outwardlyprojecting corners pulverize the ground. The turns 22 in the wings placethe dirt properly back over where the corners out under and leave it inproper shape. The edges 21 are out off and shaped so that a certainamount of dirt may fall back over the corners of the sweep, and yet notenough to cover the small crop. The sharp edges 17 allow the plow to cutthrough the ground easily and the amount of dirt which is thrown out maybe readily adjusted by the slotted connection. It is obvious thatvarious changes may be made in the details of construction withoutdeparting from this invention, and it is, therefore, to be understoodthat this invention is not to be limitedto the specific constructionshown and described.

Having thus described the invention, what is claimed is:

A plow sweep having a pair of wings eX- tending outwardly upwardly andrearwardly forming a forwardly projectingpoint, the wings terminatingrearwardly in substantially vertically arranged edges which flareoutwardly, said edges terminating in sharp corners which run under theground and pulverize the same, and said wings terminating rearwardly insubstantially horizontally arranged edges, said wings being concave andturned over at said horizontally arranged edges, the lower edges of saidwings from the point to said rear sharp corners being sharpened, for thepurpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM A. BLIZZARD.
